Hello Friend I have added hash=true and caption options to codes and sent new edited version to your e-mail. I have also updated fotorama.js from 4.6.2 to 4.6.4
Hash seems to work when I look addres bar on browser. I have set caption to be the file name of image. You can use some file names for images like this my-first-image that will be the caption. Also the hash on addres bar will be teh same as caption.
